Bias current range: 2 mA to 25 mA  
Differential modulation current range: 2.2 mA to 23 mA  
Automatic laser shutdown (ALS)  
3.3 V operation  
Compact 3 mm × 3 mm LFCSP  
Voltage-input control for bias and modulation currents  
XFP-compliant bias current monitor  
The ADN2530 laser diode driver is designed for direct modula-  
tion of packaged VCSELs with a differential resistance ranging  
from 35 Ω to 140 Ω. The active back-termination technique  
provides excellent matching with the output transmission lines  
while reducing the power dissipation in the output stage. The  
back-termination in the ADN2530 absorbs signal reflections  
from the TOSA end of the output transmission lines, enabling  
excellent optical eye quality to be achieved even when the  
TOSA end of the output transmission lines is significantly  
misterminated. The small package provides the optimum  
solution for compact modules where laser diodes are packaged  
in low pin count optical subassemblies.  
The modulation and bias currents are programmable via the  
MSET and BSET control pins. By driving these pins with  
control voltages, the user has the flexibility to implement  
various average power and extinction ratio control schemes,  
including closed-loop control and look-up tables. The eye  
crosspoint in the output eye diagram is adjustable via the  
crosspoint adjust (CPA) control voltage input. The automatic  
laser shutdown (ALS) feature allows the user to turn on/off the  
bias and modulation currents by driving the ALS pin with the  
proper logic levels. The product is available in a space-saving  
3 mm × 3 mm LFCSP specified from −40°C to +100°C.
